CONNECTING THE ANALOG OUTPUT
One 0-10vdc analog device may be controlled by the VAV / VVR, and is used to control hot water reheat or
baseboard heating valves. Figure 16 illustrates typical device connections. When connecting the actuator, make
sure to be consistent with L1 (HOT) and L2 (COMMON) connections within the system.

Typical VAV Analog Output Wiring
DANGER:
The VAV / VVR analog output is designed for use with an actuator using full-wave power.
Serious damage will occur to the VAV / VVR board if connected to a half-wave device. If unsure
about your selected actuator, call Global Control Solutions technical support.

BELIMO or OTHER ACTUATOR
24VAC TRANSFORMER
IMPORTANT !!
WHEN POWERING THE ACTUATOR
FROM THE POWER SUPPLY, MAKE
SURE THAT THE POWER IS
CONNECTED CONSISTENTLY WITH THE
VAV CONNECTION (HOT-HOT) AND
(GROUND-GROUND)
SERIOUS DAMAGE
WILL
OCCUR TO
THE VAV BOARD IF NOT CONNECTED
CORRECTLY !
